Volume changes or mute doesn't work on some games
Summary
It started happened for a month now in rFactor 1 and thought Windows broke some compatibility setting. But it happens on WWE 2K23 so I suposse there's something broken here.
Changing the volume or muting doesn't change the volume of the game. (It only works visually, I hear it at 100% always)
Changing the output device works perfectly.
Volume control and mute options works on other programs as Discord and Chrome.
This only seems to affect some games.
Steps to reproduce
-
Open any game
-
Change volume or mute that game
-
See it changes visually on Ear Trumpet bar but you can still hear it at 100% no matter the setting.
-
Open OBS
-
Add audio capture input
-
Select the game
-
See how volume changes affect the audio input of the game
-
Keep hearing the game at 100% in the output device.
EarTrumpet version
2.3.0.0
Windows version
10.0.19045.4291

After testing, I can ensure this happens in all games I have: Valorant, Circuit Superstarts, etc.
I just never needed to reduce the volume of them before, that's why I never noticed.
Did more testing it does affect OBS audio capture volume, but I can still hear the game at 100% in my headset.
With OBS open for some reason the mute function started working again...
This is typically an issue with the app/game, or sometimes Windows, not EarTrumpet. Can you verify you see the same issue with the built-in Volume Mixer? (Start > Run > sndvol.exe)
I little bit late, but I have the same issue on some games. One for sure that I am playing now is Ghost of Tsushima, and I can confirm that the issue is present also on sndvol.exe
